Bulgarian Prime Minister Boyko Borisov on Tuesday revealed new details
regarding the activities of the terrorists who perpetrated the suicide
bombing in Burgas against a group of Israeli tourists last week, the
Bulgarian Sofia News Agency reported.

"They came about a month
before that, they changed leased vehicles, they moved in different
cities so as not to be seen together, and no two of them can be seen in
one place on any security camera," Borisov told Sofia News Agency,
adding that the people behind the horrific blast had been "exceptionally
skilled."

"The services worked perfectly but the manner in which
the attack was carried out indicates it could not have been prevented,"
he emphasized, according to the report.

Bulgaria's prime minister indicated that even if the terrorists had not attacked the
Israeli tourists at Burgas Airport, they still could have followed the
tourists' bus to their hotel and detonated a bomb there.

"We are
very vulnerable. You can enter Bulgaria from any place as a tourist, an
expert, or a guest in the mixed-population areas, but our services do
not have multi-billon budgets," he declared, said the report.

According
to Sofia, Borisov still highlighted that the investigation was moving
forward and he contended that Bulgarian services were on par with other
nations services which investigated the September 11 attacks and the
Madrid train bombings.
